I think there’s a planet which pass brown dwarf limit but not become a brown dwarf

I think probably there's a chance planet pass even above Deutronium fusion limit's without make that planet become brown dwarf.

‎The one of my argument was the planet made by degenerate matter.
‎
‎Imma use example
‎GP Comae Berenices b
‎Radius:29,600 km
‎mass:10.5+1.5 Jupiter
‎
‎GP comae Berineces b have density at least >185 g/cm³ (yeah it's degenerate matter).
‎Theoretical models suggest that a planet or stellar remnant composed solely of ordinary matter cannot exceed a density on the order of 30 g/cm.
‎
‎
‎
‎GP Comae Berenices b originally a red dwarf orbiting a white dwarf named G-61 29 (actually there's no official named of that white dwarf besides GP comae Berineces, but I use‎ G-61 29 since it's kinda cool).

‎
‎G-61 29
‎mass:0.59 ± 0.09× sun
‎Radius:9,000 km
‎Temperature:14,800±500 kelvin
‎Density:386,000 g/cm³.
‎
‎The red dwarf orbiting very close to a G-61, to close that white dwarf absorbing almost red dwarf materials into accreditation disk, this happen so violent that just left pure degenerate matters which is now was a GP Comae Berenices b and both was got classification as AM Canum Venaticorum (AM CVn) system. a very rare type of cataclysmic binary star system in which both objects are depleted of hydrogen
‎
‎So yeah in nutshell
‎Red dwarf>swallowed by white dwarf>losses all matter and mass>just left a degenerate matter>become a planet
‎
‎some Suggest takes that GP comae Berineces b was a white dwarf remnant from white dwarf collision with a ‎G-61 29.
And the star collapse with ‎G-61 29 and just leaving degenerate Matter.
‎
‎
‎
‎my idea was there's a planet pass 13× Jupiter mass
‎And the materials was from a degenerate Matter.
‎And I think degenerate matter cannot start a Deutronium fusion
‎Since

‎•Degeneracy alone doesn't cause fusion—it's quantum pressure, not energy release
‎
‎•deuterium fusion reactions depend on sufficient temperature, density, and composition
‎
•‎Degenerate Matter: This occurs in compact objects where electrons (or other particles) are packed so densely that quantum effects (Pauli exclusion principle) dominate, providing pressure independent of temperature.dd56d6 It's common in white dwarfs, neutron stars, and the cores of massive gas giants or brown dwarfs. In these, the matter can be "cold" (relatively low temperature) yet stable due to degeneracy.

‎Probally there ton and loot of miss information so correct this one and if you have way to made a planet up to 13× Jupiter mass without Deutronium fusion.
‎

‎And idk why I'm so obsessed with this one
